High pressure heater overview
High pressure heater is use for heating boiler feed water to reach the required temperature by the steam extraction of steam turbine, increase the thermal efficiency of power plants.
The device is composed of shell and tube system, the upper shell inside set steam condensation section, set the hydrophobic water cooling at the bottom, the top of the inlet and outlet pipe set feed water inlet and outlet. When super-heated steam get into the shell by inlet, the feed water of upper main spiral tube can be heated, after the steam condenses into water, part of the feed water of the lower hydrophobic cold spiral tube can be heated by the hot water of condensation.
After being used the condensate was drained out by the hydrophobic export. This device has low energy consumption, compact structure, less occupied area, material consumption saving etc, can control of hydrophobic water velocity more strictly and narrow hydrophobic terminal difference.
Low pressure heater overview
As both high pressure heater and low pressure heater belong to the feed water heater, in terms of feed water flow, low pressure heater layout after the export of the condensate pump and before the deaerator, feed water flow over the low pressure heater without deaerator deoxidize, so water has high oxygen content then add equipment corrosion to the heater, so the heat exchange tube often use stainless steel tube or thick wall steel tube."Low pressure heater" classification, according to the internal structure are: the U-shaped tube plate type, box (including: spiral pipe, waist round tube, coil box)type, serpentine outside the tube box type, etc. U-shaped tube plate type has many advantages: compact structure, small water resistance, easy to layout overheat and hydrophobic cold section, achieve full reflux, convenient maintenance, widely applied, can be designed as vertical, inverted vertical and horizontal layout according to customer's site installation arrangement.
